Naphthenic acids are recognized as the main corrosive species in acidic crude oils,
although they represent less than 3 wt%. Alternative methods have been developed in an …

Naphthenic acid (NA) has been recognized as one of the major sources of corrosion in oil
production and refining. In this study, catalytic decarboxylation of carboxylic acid model …

Although the term “naphthenic acids” was originally used to describe acids that contain
naphthenic rings, today this term is used in a more general sense and refers to all …

Refining of high acid crudes (HACs) is seriously limited by extensive corrosion of refinery
equipment due to the presence of intrinsic naphthenic acids (NAs). Herein, in the absence of …

In the past three years, we followed the work plan as we suggested in the proposal and
made every efforts to fulfill the project objectives. Based on our large amount of creative and …

Although the term “naphthenic acids” was originally used to describe acids that contain
naphthenic rings, today this term is used in a more general sense and refers to all cyclic …

Catalytic deacidification is a fascinating method to decrease the naphthenic acids (NAs)
concentration of highly acidic petroleum crude because these acids caused serious …

The naphthenic acids found in petroleum may cause serious corrosion problems for
processing equipment. In this study, naphthenic acids were removed by catalytic …

Naphthenic acids (NAs) are widely present in crude oil and oil sands process-affected water
(OSPW). NAs in crude oil lead to corrosion problems, promote emulsion formation, decrease …

Naphthenic acids (NAs) are naturally occurring organic acids present in crude oil and
bitumen as contaminants. Their presence in the crude oil greatly reduces the quality and …
